Re: [PATCH] Deprecate use of stdio

I've been playing with sfio on Solaris quite a bit recently and I've had our site working on iPlanet with sfio for a couple of weeks. Seems to be doing okay so far with something between 4.3.1 and 4.3.2. Getting sfio to link was a bit of pain in the arse at first, but it came down to a couple of simple LIBS arguments to get it going. As you say, fixing the problem at the root would be preferable, but sfio might be a decent intermediary step. I can test the patches and such on Solaris 8 SPARC, and if you (or anybody who needs it, within reason of course) would like access to a Solaris shell, I can arrange it. (It's slightly limited by a 300 MB quota, but that's pretty much it.)
